Can I rely on negative HIV and western blot test reports after 56 days of exposure?

Hello doctor,

How accurate are HIV tests done in the laboratory on the 56th day of exposure along with the western blot test? Both tests came negative. I took the flu vaccine 18 days before the test and had no symptoms except minor rashes.

Kindly help.

Hello doctor,

Thank you for your reply.

The exposure was unprotected vaginal sex. Therefore, the Ab and Ag test was done along with the western blot simultaneously.

I am attaching the complete reports. Today is the 71st day with no fever.

So here are my queries.

1. Should I do the tests again after 90 days?
2. Or should I undergo any tests in between this period?
3. Does the flu vaccine that I took 18 days before testing could have any effect on the result?

Kindly help.

Hello doctor,

Thank you for your reply.

She was not a sex worker. She is a housewife, has a son, and resides with her husband. She is an unfamiliar person to me. She had no skin diseases or rashes—no coughing for that brief period. Total exposure was of four to five minutes.

After 28 to 30 days, I felt feverish with a temperature of 98.0 degrees Fahrenheit to 98.3 degrees Fahrenheit for five to six days, which was when I took the flu vaccine, and the tests were done after 19 days of flu vaccine administration.

Kindly help.
